It provides the following functionality for ubuntu cloud image deployments:

• Image Provisioning.
• Networking setup.
• Kernel setup.
• Diagnostics setup.
• SCVMM Deployments
• VM Extensions Management

For a more detailed list of functionallity this package provides to ubuntu cloud images, refer to the upstream project page at github: https://github.com/Azure/WALinuxAgent

QA Process

This is the mandatory QA process that the proposed walinuxagent packages have to pass. The following requirements must be met:

• The new package candidate version is to be placed on a PPA and tested manually on the target suite during upstream changes packaging phase. This tests include:
  • Installing the PPA packages on an Azure VM, restore the VM to a first boot state and reboot it.
  • Or might require to generate an image with the PPA package version preinstalled and test that directly.
• Once the manual packaging tests pass succesfully and the package seems to require no more changes, a test image is required to be generated having the PPA package version preinstalled before CPC Cloudimages Automated Testing can be done.
• CPC Couldimages Automatic Testing will run the test image of target suite through a series of tests for all relevant Azure VM sizes. Currently those tests include:
  • Azure general tests
  • Ubuntu basic tests
  • Cloud-init tests
  • Walinuxagent regresion tests
